Air conditioning system and railway train equipped with the same

The present invention relates to an air conditioning system for adjusting the temperature and humidity of a passenger compartment in a railway vehicle, and a railway train including the same.

Railway vehicles are equipped with an air conditioning system for adjusting the temperature and humidity of the passenger cabin. This air conditioning system has two types: a distributed type in which a plurality of air conditioners are distributed on the roof structure, and a centralized type in which only one air conditioner is arranged on the roof structure near the center of the vehicle body. Etc., the latter centralized air conditioning system is mainly adopted. This centralized air conditioning system includes an air conditioning duct, and the air conditioning duct is provided on the ceiling behind the cabin (the roof structure). The air-conditioning duct is formed with a blow-out opening, and the air-conditioned air distributed from the air-conditioning apparatus to the air-conditioning duct is blown out into the cabin through the blow-out opening. As an air conditioning system configured in this way, there is an air conditioning system as described in Patent Documents 1 to 3, for example.

In the air conditioning systems described in Patent Documents 1 to 3, a plenum chamber type structure is adopted for the air conditioning duct. In this air conditioning duct, a partition wall portion is provided in the air conditioning duct. The partition wall portion extends from one end to the other end of the air conditioning duct in the longitudinal direction of the vehicle body, and is divided into a main duct located near the center in the vehicle width direction and a sub duct located outside in the vehicle width direction. ing. The main duct and the sub duct are connected via a gap above the partition wall, and the conditioned air supplied from the air conditioner to the main duct enters the sub duct through this gap and blows out from the outlet. Yes.

In the air conditioning system having such a configuration, the air velocity distribution of the conditioned air is made uniform over the entire longitudinal direction of the vehicle by adjusting the cross-sectional area and volume ratio of the main duct and the sub duct, and the size of the gap connecting them. .

However, in the structure of the plenum chamber system employed in the air conditioning systems described in Patent Documents 1 to 3, in order to determine the optimal volume ratio, gap size, etc., so that the air velocity distribution of the conditioned air is uniform over the entire vehicle longitudinal direction. The relational expression has not been established yet. Therefore, a full-scale test duct was created and tested, and an actual air-conditioning duct was designed and manufactured based on the test duct and installed in the vehicle. is doing. If the wind speed distribution is not as predicted in this final confirmation, the shape of the partition wall between the main duct and sub duct must be corrected, and the wind speed distribution of the conditioned air blown from the outlet However, it is difficult to manufacture a uniform air conditioning system over the entire longitudinal direction of the vehicle.

Therefore, an object of the present invention is to provide an air conditioning system that is easy to manufacture and has a uniform air velocity distribution of the conditioned air blown from the blowout port over the entire longitudinal direction of the vehicle.

An air conditioning system for a railway vehicle according to the present invention includes a ventilation duct extending in a longitudinal direction of the railway vehicle, and an air conditioning duct having a plurality of outlets communicating the ventilation path and a guest room of the railway vehicle. An air conditioner that supplies conditioned air to the ventilation path of the air conditioning duct, and a flow rate adjustment that is provided downstream of the air conditioner in the ventilation path and regulates the flow velocity by inhibiting the flow of the conditioned air in the longitudinal direction of the vehicle And a member.

According to the present invention, the flow rate of the conditioned air can be suppressed by inhibiting the flow of the conditioned air in the longitudinal direction of the vehicle. Thereby, the wind speed distribution of the conditioned air blown from the outlet can be made uniform throughout the longitudinal direction of the vehicle.

Further, in the present invention, the air velocity distribution of the conditioned air blown from the outlet can be made uniform over the entire longitudinal direction of the vehicle simply by providing a flow rate adjusting member in the ventilation path. It is not necessary to repeatedly adjust the cross-sectional area, volume ratio, and gap size, and the manufacturing is easy.

According to the present invention, it is possible to provide an air conditioning system that is easy to manufacture and that has a uniform air velocity distribution over the entire longitudinal direction of the vehicle.

Hereinafter, the

air conditioning systems

1, 1 </ b> A, 1 </ b> B of the railway vehicle according to the embodiment of the present invention will be described with reference to the drawings described above. The concept of the direction in each embodiment is the same as the concept of the direction when the traveling direction of the railway vehicle (hereinafter, also simply referred to as “vehicle”) 2 is set to the front and turned forward. That is, the vehicle longitudinal direction corresponds to the front-rear direction, and the vehicle width direction corresponds to the left-right direction. The railway vehicle air conditioning system 1 described below is only one embodiment of the present invention. That is, the present invention is not limited to the following embodiments, and additions, deletions, and changes can be made without departing from the spirit of the invention.

<First Embodiment>
[Air conditioning system]
As shown in FIG. 1, the vehicle 2 includes an air conditioning system 1 for adjusting the temperature and humidity of the passenger compartment 2a therein. The air conditioning system 1 basically includes an air conditioner 3, an air conditioning duct 4, an air conditioning member 5, and a flow rate adjusting plate 6. The air conditioner 3 is provided on the roof structure 7 so as to be positioned at the center portion in the front-rear direction, and is configured to be able to supply conditioned air. In addition, a pair of air conditioning ducts 4 arranged symmetrically are provided in the roof structure 7. The left and right air conditioning ducts 4 have the same configuration except that the respective configurations are arranged symmetrically. Therefore, only one air conditioning duct (right air conditioning duct) 4 is illustrated and described below, and the description and illustration of the other air conditioning duct are omitted.

[Air conditioning duct]
The air conditioning duct 4 is a substantially rectangular cylindrical member and extends from the front end to the rear end of the vehicle 2. A partition plate (not shown) is provided in the air-conditioning duct 4 at the center in the front-rear direction, and the air-conditioning duct 4 is divided into two in the front-rear direction by the partition plate. By dividing into two in this way, the ventilation path 4a is formed in the air conditioning duct 4 on the front side and the rear side of the partition plate, respectively. The ventilation path 4a extends in the front-rear direction, has a rectangular cross section, and has a single shape. That is, the air-conditioning duct 4 has only the ventilation path 4a which is a main duct in the air-conditioning duct 4 and has no sub-duct in the air-conditioning duct having a plenum chamber structure. Therefore, since there is no partition wall part for partitioning the main duct and the sub duct as in the prior art, it is not necessary to modify the shape of the partition wall part, and manufacturing is easy.

The ventilation path 4a thus formed as a single shape is arranged symmetrically with respect to the partition plate and has the same configuration. Therefore, only one of the ventilation paths 4a is illustrated and described below, and the description and illustration of the other ventilation path are omitted. The ventilation path 4 a formed in this way is connected to the air conditioner 3.

The air conditioner 3 is provided in the roof structure of the vehicle 2, and is arrange | positioned corresponding to every ventilation path 4a. In the present embodiment, since four ventilation paths 4 a are formed for each vehicle 2, each vehicle 2 has four air conditioners 3. The air conditioner 3 is configured to supply conditioned air, and is concentrated on the center of the vehicle 2 in the front-rear direction. The air conditioner 3 and the ventilation path 4a are connected to one end side of the ventilation path 4a that is the partition plate side, and the conditioned air from the air conditioner 3 is supplied thereto. Thereby, the flow of conditioned air is formed in the ventilation path 4a from the one end side to the other end located outside in the front-rear direction.

The air conditioning duct 4 is formed with a mounting groove 4b that is recessed upward at the outer side in the vehicle width direction at the lower end thereof. The ceiling portion of the mounting groove 4b connects the ventilation path 4a and the vehicle compartment 2a. A plurality of outlets 4c are formed. The outlet 4c is formed in a slit shape extending in the front-rear direction, and is arranged at equal intervals in the front-rear direction. In addition, an air conditioning member 5 is provided in the mounting groove 4b.

[Air conditioning member]
As shown in FIG. 3, the air conditioning member 5 is a member having a U-shaped cross section made of, for example, a light alloy shape or FRP, and extends in the front-rear direction. The air conditioning member 5 is fitted into the mounting groove 4b so that the opening portion 5a is positioned below. A plurality of blowing holes 5 b are formed in the ceiling portion of the air conditioning member 5. The blowout hole 5b which is the first blowout hole is a slit-like hole extending in the front-rear direction, and the width h1 in the left-right direction is narrower than h2 than the width in the left-right direction of the opening portion 5a. Further, a sponge-like seal member 8 is provided on the top surface of the air conditioning member 5 so as to surround the blowout hole 5b. The seal member 8 is interposed between the air conditioning member 5 and the air conditioning duct 4, and seals between them so as to be connected to the blowout hole 5 b and the blowout opening 4 c of the air conditioning duct 4.

Further, a plurality of air conditioning plates 9 are provided in the air conditioning member 5. The air conditioning plate 9 protrudes downward from the ceiling surface of the air conditioning member 5 and extends in the left-right direction so as to cross the blowing hole 5b. The air conditioning plates 9 are arranged on the air conditioning member 5 at equal intervals, that is, in a louver shape. As a result, a blowout hole 5c (second blowout hole) that is long in the left-right direction is formed in the opening 5a of the air conditioning member 5. As a result, the air conditioning member 5 has a double structure having a slit-like blowing hole 5b extending in the front-rear direction on the upper side and a blowing hole 5c long in the left-right direction on the lower side.

The air conditioning member 5 having a double structure as described above restricts the amount of air blown from the upper blowing hole 5b, and the lower blowing hole 5c (hereinafter, also simply referred to as “lower blowing hole 5c”). The direction of the conditioned air coming out of the upper blowing hole 5b (hereinafter also simply referred to as “upper blowing hole 5b”) is changed vertically downward. The flow of the conditioned air will be described more specifically. The conditioned air flowing through the ventilation path 4a of the air conditioning duct 4 is guided to the upper outlet hole 5b through the outlet 4c. Since both the air outlet 4c and the upper air outlet 5b are formed in a slit shape, the conditioned air is blown out from the upper air outlet 5b while having a velocity component in the front-rear direction. Below the upper blowing hole 5b, a wider space is formed between the adjacent air conditioning plates 9, and the conditioned air can be diffused in the left-right direction and blown out by this space. Furthermore, when the conditioned air blown from the upper blowing hole 5b hits the air conditioning plate 9, the flow can be directed vertically downward. Thus, by using the air conditioning member 5, the conditioned air blown from the air conditioning duct 4 can be diffused in the left-right direction and the flow can be directed vertically downward.

[Baffle plate]
The air conditioning duct 4 is provided with a baffle plate 10 at the ceiling of the mounting groove 4b and directly below the air conditioner 3 (specifically, a portion on one end side of the ventilation path 4a). The baffle plate 10 is a strip-shaped plate member extending in the front-rear direction, and is provided so as to be interposed between the ceiling portion of the mounting groove 4 b and the seal member 8. The baffle plate 10 is formed with a slit 10a that is narrower than the air outlet 4c, and the slit 10a is adapted to restrict the conditioned air that is guided to the upper air outlet 5b through the air outlet 4c. In the present embodiment, the width of the slit 10a is about half the width of the outlet 4c, but is not limited to this width.

[Flow rate adjusting plate]
Further, a flow rate adjusting plate 6 is provided in the ventilation path 4 a of the air conditioning duct 4. The flow rate adjusting plate 6 that is a flow rate adjusting member is a so-called plate-like net member (for example, a net plate having an aperture ratio of 80% or more), and has a frame 6a having substantially the same shape as the cross section of the ventilation path 4a. The flow rate adjusting plate 6 is fitted upright in the ventilation path 4a, obstructs the flow in the front-rear direction of the conditioned air flowing through the ventilation path 4a, and the velocity component in the front-rear direction (hereinafter, simply “ It is also referred to as “flow velocity in the front-rear direction”) and the pressure is reduced, that is, the air flow is resisted to reduce the flow velocity and pressure in the front-rear direction.

The flow rate adjusting plate 6 configured in this way is provided on the downstream side from the position where the conditioned air is supplied from the air conditioner 3 in the ventilation path 4a (that is, directly below the air conditioner 3). More specifically, the flow rate adjusting plate 6 is located in an installation region that is separated from the one end by L / 10 to L / 3 with respect to the distance L between the one end and the other end of the ventilation path 4a. 6 is arranged. In this installation region, the flow velocity in the front-rear direction of the conditioned air is large compared to other regions, and the pressure of the conditioned air is reduced. Therefore, the air volume from the lower outlet 5c located in the installation area is smaller than that of the lower outlet 5c located in the other area. By arranging the flow rate adjustment plate 6 in such an installation area, the flow rate in the front-rear direction of the conditioned air can be suppressed to increase the pressure of the conditioned air, and the air volume from the lower outlet 5c located in the installation area can be reduced. Can be increased. In addition, for example, when the length of the air conditioning duct 4 in the longitudinal direction of the vehicle is 19.14 m, the installation position of the flow rate adjusting plate 6 is preferably arranged at a position near 2 m forward and backward from the center of the air conditioner 3. The installation position of the flow rate adjusting plate 6 may be adjusted based on various factors such as the size of the air conditioning duct and the number of air conditioners.

Further, the air volume from the lower outlet 5c corresponds to the flow velocity in the front-rear direction of the conditioned air flowing therethrough, and the air volume from the lower outlet 5c decreases as the flow velocity increases. In the installation area, the air volume is minimized at a position where the flow velocity in the front-rear direction of the conditioned air is the highest, that is, the fastest position where the flow velocity in the front-rear direction of the conditioned air flowing through the ventilation path 4a is the highest. Therefore, it is preferable to suppress the flow rate in the front-rear direction of the conditioned air at the fastest position, and it is preferable to arrange the flow rate adjusting plate 6 on the downstream side near the fastest position. Therefore, in the present embodiment, the flow rate adjusting plate 6 is disposed on the downstream side near the fastest position.

[Functions of air conditioning system]
Hereinafter, the function of the air conditioning system 1 will be described more specifically with reference to FIG. FIG. 5 shows the wind speed (vertical axis) blown into the vehicle compartment 2a from the lower blowing holes 5c arranged from one end to the other end of the ventilation path 4a, and each number (horizontal axis). Are attached in order from the lower blowing hole 5c closest to the other end of the ventilation path 4a. That is, the lower blowing hole 5c closest to the other end of the ventilation path 4a is No. 1, and the lower blowing hole 5c located at one end of the ventilation path 4a, that is, directly below the air conditioner 3, is No. 43. ing. Further, the black bar graph indicates the wind speed from each lower blowing hole 5c when the baffle plate 10 and the flow velocity adjusting plate 6 are provided as in the air conditioning system 1, and the white bar graph indicates the air conditioning system 1. 5 shows the wind speed from each lower blowing hole 5c when the baffle plate 10 and the flow velocity adjusting plate 6 are not provided.

As can be seen from FIG. 5, since the air conditioner 3 supplies the conditioned air directly below (supply direction), when the baffle plate 10 is not provided, the lower side located directly below the air conditioner 3. The conditioned air is blown directly from the blowing holes 5c (No. 42 and No. 43), and the air speed of the conditioned air blown from there is relatively higher than the wind speed in the other lower blowing holes 5c. On the other hand, in the air conditioning system 1, the baffle plate 10 is provided in the lower blowing hole 5 c (No. 42 and No. 43) located directly below the air conditioner 3, and the baffle plate 10 directly below the air conditioner 3. The amount of blowing is reduced from the lower blowing hole 5c (42 and 43) located. This restricts the air volume of the lower blowing holes 5c (No. 42 and No. 43) located immediately below the air conditioner 3, and improves the uniformity of the air velocity distribution of the conditioned air blown out from each lower blowing hole 5c. be able to.

Regardless of the presence or absence of the baffle plate 10, a part of the conditioned air is repelled on the lower surface of the air conditioning duct 4 without coming out from the lower blowing hole 5 c located directly under the air conditioning device 3. In the immediate area located immediately downstream of the air conditioner 3, the bounced conditioned air flows toward the ceiling of the air conditioning duct 4 and flows to the other end of the ventilation path 4 a. In this immediate area, the air-conditioning wind is in a turbulent state by being bounced, and the flow is directed to the ceiling. Therefore, the lower blowing holes 5c (No. 40 and No. 40) located on the air conditioner 3 side in the immediate area No. 41) is drastically reduced. Furthermore, since the conditioned air is in a turbulent state in the immediate area, the flow velocity in the front-rear direction is larger than in other areas. The amount of air blown out from each blowing hole 5c corresponds to the flow velocity in the front-rear direction of the conditioned air except for the lower blowing holes 5c (No. 40 and No. 41) having a large ceiling-oriented component. Therefore, when the baffle plate 10 and the flow rate adjustment plate 6 are not provided, the air speed of the conditioned air blown out from the blowout holes 5c (36th to 41st) located in the nearest region is relative to the wind speed in the other blowout holes 5c. The flow velocity in the front-rear direction is minimized at the lower blowing hole 5c (No. 36) near the fastest position where the fastest speed is reached.

On the other hand, in the air conditioning system 1, the flow rate adjusting plate 6 is provided in the vicinity of the fastest position and on the downstream side (between No. 35 and No. 34). The flow rate and pressure drop of the conditioned air at the fastest position and upstream thereof can be suppressed. As a result, it is possible to adjust the excess and deficiency of the amount of air blown by increasing the air speed of the conditioned air blown out from the lower blowing holes 5c (No. 36 to No. 41) located in the nearest region.

Moreover, the flow velocity adjusting plate 6 has a rectification function, and rectifies the formed turbulent flow. The amount of supply to the lower blowing holes 5c (No. 36 to No. 41) located in the nearest area was insufficient due to the turbulent flow of the conditioned air, but by rectifying the conditioned air as described above By increasing the supply amount, it is possible to increase the air speed of the conditioned air from the lower blowing holes 5c (36th to 41st) located immediately next to the above.

As described above, in the air conditioning system 1, it is possible to increase the air speed of the conditioned air blown out from the lower blowing holes 5 c (No. 36 to No. 41) located in the immediate area, and the lower side located directly below the air conditioner 3. The wind speed of the conditioned air blown out from the blowing hole 5c can be suppressed. Thereby, the uniformity of the wind speed distribution of the conditioned air blown out from each lower blowing hole 5c can be improved.

Also, in the ventilation path 4a, the other end is blocked, so the conditioned air flowing from the upstream is rebounded at the other end. In the structure in which the flow rate adjusting plate 6 is not provided, the conditioned air bounces back against the other end of the ventilation path 4a while maintaining the flow rate. For this reason, the pressure of the conditioned air at the other end of the ventilation path 4a increases, and the wind speed of the conditioned air blown out from the lower blowing holes 5c (No. 1 to 15) located near the other end of the ventilation path 4a is relatively high. It is getting bigger. On the other hand, in the air conditioning system 1, the flow rate near the other end of the ventilation path 4a can be stabilized by suppressing the flow rate of the conditioned air flowing downstream from the flow rate adjustment plate 6 by the rectifying action of the flow rate adjustment plate 6. As a result, an increase in the pressure of the conditioned air can be suppressed, and the conditioned air blown out from the lower blowing holes 5c (# 1 to 15) located near the other end of the ventilation path 4a can be suppressed. Therefore, the non-uniformity in the flow velocity distribution of the conditioned air flowing through the ventilation path 4a can be suppressed, and the uniformity of the conditioned air velocity blown out from each lower blowing hole 5c can be further improved.

[Other configurations]
Moreover, the lighting equipment 11 extended in the front-back direction is provided in the left-right direction outer side of the air-conditioning duct 4, and the side ceiling 12 is located in the outer side. Further, a cross-flow fan 13 (blower) is provided between the pair of air-conditioning ducts 4 so as to be positioned at the center in the left-right direction of the vehicle 2. To be blown out. Further, another air conditioning member 14 is provided below the cross flow fan 13. The air conditioning member 14 is a plate-like member and is provided so as to cover the cross flow fan 13 from below. This air conditioning member 14 has a plurality of air conditioning plates 16 on its lower surface.

The air conditioning plate 16 extends in the front-rear direction, and projects obliquely downward toward the outer side in the left-right direction on the lower surface of the air conditioning member 14. The air conditioning plates 16 having such a shape are arranged side by side in the left-right direction, that is, arranged in a louver shape. The air conditioning member 14 is formed with slit-shaped blowing holes 14 a between the adjacent air conditioning plates 16. Further, the blowout holes 14a are arranged in parallel in the front-rear direction between the adjacent air conditioning plates 16. The conditioned air from the cross flow fan 13 is blown out to the passenger compartment 2a through the blow hole 14a, and its direction is changed obliquely downward toward the outer side in the left-right direction by the wind regulating plate 16.

The air-conditioning system 1 configured as described above uses the air-conditioning duct 4 in which the ventilation passage 4a is formed in a single unit, and further arranges the flow rate adjusting plate 6 near the fastest position and on the downstream side thereof. Therefore, the number of parts is small and the structure is simple. Therefore, compared to the plenum chamber type air conditioning system, the air conditioning system 1 can be easily manufactured, its manufacturing cost is low, and further weight reduction is possible.

<Second Embodiment>
The air conditioning system 1A of the second embodiment is similar in configuration to the air conditioning system 1 of the first embodiment. Below, about the structure of 1 A of air conditioning systems of 1st Embodiment, only a different point from the structure similar to the air conditioning system 1 of 1st Embodiment is demonstrated, and the description is abbreviate | omitted about the same point. The same applies to the air conditioning system 1B of the third embodiment.

Further, a seal member 8A is provided on the lower surface of the air conditioning duct 4A so as to surround the outlet 4c. Further, an air conditioning member 5A is detachably provided below the air conditioning duct 4A.

[Air conditioning member]

air conditioning members

5 and 14 of the first embodiment. The air conditioning member 5A has a plate-shaped flat portion 5d formed in a rectangular shape extending in the front-rear and left-right directions. The flat portion 5d is installed on the two lighting devices 11 so as to pass between the two lighting devices 11 located on both the left and right sides, and covers the air conditioning duct 4A and the cross flow fan 13 from below. A slit-like upper blowing hole 5b is formed in the flat part 5d so as to overlap the blowing hole 4c in the vicinity of both ends in the left-right direction. By forming the seal member 8A so as to overlap, the seal member 8A is disposed so as to surround the upper blowout hole 5b, and the blowout port 4c and the upper blowout hole 5b are connected by the inner hole of the seal member 8A. Further, a substantially rectangular blowout window 5e is formed in the flat portion 5d at the center portion in the left-right direction, and the conditioned air from the cross-flow fan 13 blows out from the blowout window 5e. Further, the flat surface portion 5d has a plurality of air conditioning plates 9A on the lower surface thereof.

The air conditioning plate 9A is a plate-like member extending in the left-right direction, and is suspended so as to protrude vertically downward from the lower surface of the flat portion 5d. The air conditioning plates 9A are arranged at equal intervals in the front-rear direction. The air conditioning plate 9A arranged in this way extends linearly from the left end to the right end of the flat surface portion 5d, and is formed at the upper blowing hole 5b and the central portion formed at the left and right end portions of the flat surface portion 5d, respectively. It is formed so as to cross the blowing window 5e. By arranging the air conditioning plate 9A in this way, the air conditioning member 5A can have a double structure as in the air conditioning member 5 of the first embodiment, and the conditioned air from the outlet 4c and the cross flow fan 13 can be transmitted in the left-right direction. And the flow can be directed downward.

Moreover, since the air conditioning member 5A is configured to cover the air conditioning duct 4A and the crossflow fan 13 from below, the air conditioning duct 4A, the crossflow fan 13, and other devices disposed in the roof structure 7 are covered. be able to. Further, since the air conditioning member 5A is obtained by integrating the two

air conditioning members

5 and 14 of the first embodiment, the number of parts can be reduced, and the work process of the assembling work can be reduced. Thereby, the beauty | look of the ceiling of the compartment 2a can be improved, suppressing a number of parts.

[inspection door]
An inspection port 21 is formed in the air conditioning duct 4A as shown in FIG. The inspection port 21 is formed in a substantially rectangular shape when viewed from below. An inspection lid 22 is provided at the inspection port 21 so as to be openable and closable. The inspection port 21 and the inspection lid 22 are covered with the air conditioning member 5A at a normal time other than when the air conditioning duct 4A and the flow velocity adjusting plate 6 are inspected and cleaned, and are not visible from the passenger compartment 2a. It can be seen from the passenger compartment 2a by removing 5A. By removing the inspection lid 22 after the removal, the inside of the air conditioning duct 4A can be seen through the inspection port 21 or the inside thereof can be cleaned.

Since the inspection port 21 configured as described above can be hidden from the passenger compartment 2a by the air-conditioning member 5A as described above, its formation position and shape can be appropriately selected. By appropriately selecting in this way, inspection and cleaning work in the air conditioning duct 4A can be easily performed. In the present embodiment, the inspection port 21 is formed at the fastest position so that the flow rate adjusting plate 6 can be easily inspected.

<Third Embodiment>

In the air conditioning duct 4B, the air conditioning member 5B configured in this manner applies the air conditioning airflow that flows from the center in the front-rear direction toward the end portion to the air conditioning plate 9B, changes the direction of the airflowing air flow vertically downward, and then blows into the upper blowing hole. It is made to blow out from 5b. Moreover, the upper blowing hole 5b is formed in a slit shape, whereby the conditioned air that has passed through the upper blowing hole 5b can be diffused in the left-right direction. That is, the conditioned air can be blown downward while being diffused in the left-right direction by the air-conditioning member 5B.

Further, the air conditioning member 5B can be made of either a light alloy shape material or FRP material. In the case of using a light alloy profile, the air conditioning member 5B can be manufactured simply by cutting the light alloy profile, and the structure is simple. On the other hand, when configured by FRP, the shield plate 23, the

side plates

24L and 24R, and the wind control plate 9B can be configured to be bonded with an adhesive or fastened with screws, so that each configuration is separately It can be configured and the color etc. can be changed freely. That is, the degree of freedom in designing the air conditioning member 5B can be improved.

In addition, the air conditioning system 1B of the third embodiment has the same effects as the air conditioning system 1A of the first embodiment.

<Other embodiments>
In the first to third embodiments, the flow rate adjusting plate 6 is light in weight, can suppress the resistance given to the conditioned air flowing in the air conditioning duct 4, and further, by changing the density and thickness of the wire material in the net portion. Since the resistance can be changed, a plate-like net member is preferable, but the shape is not necessarily limited thereto. The flow rate adjusting plate 6 may be a punching plate having a plurality of through holes (for example, an aperture ratio of about 50%), or may be a simple plate member having an outer dimension smaller than the cross-sectional area of the air conditioning duct 4. Good. That is, any member can be used as long as it can inhibit the flow of the conditioned air flowing through the ventilation path 4a to reduce the flow velocity and has a wind regulation effect. The arrangement position of the air conditioner 3 is not limited to one end of the ventilation path 4a, and may be the other end of the ventilation path 4a. The number of air conditioners 3 is not limited to one for one ventilation path, but may be two or more for two ventilation paths, or one for two ventilation paths. Also good.

Further, the vehicle 2 includes a vehicle room 2 a having only a guest room and a vehicle 2 having a guest room and an entrance / exit, and may be an air conditioning system that supplies conditioned air only to the guest room or the entrance / exit.
